Application filed. June 6, 1914. Serial No. 843,408.

To all whom it may concern:

Be it known that I, Bonner JAGKSON, a citizen of the United States, anda resident of Homer, in the county of Clairborne and State of Louisiana,have invented certain new and useful Improvements in Dikes, of which thefollowing is a specification, reference being had to the accompanyingdrawings, forming a part of this specification.

The invention has for'its object to guard against the submergence oflow-lands, as for instance, in reclaiming such lands, particularly of afertile character.

A further object is to carry out the aforesaid ends in an economical,simple and effective manner and with facility.

The invention therefore consists of certain structural features,including the combination and arrangement of parts substantially ashereinafter fully disclosed and defined by the appended claim.

In the accompanying drawings is illustrated the embodiment of myinvention wherein it will be understood that various changes andmodifications as to the detailed construction and arrangement of partsmay be made without departing from the spirit of the invention, and inwhich drawing:

Figure 1 is a side elevation of my invention as applied for the dikingoff a lowland.

Fig. 2 is a transverse section thereof taken through the gate.

Fig. 3 is also a like section upon an enlarged scale, taken at a pointdisclosing more especially the concrete base at the bottom of the dike.

Fig. 4 is an opposite or inside elevational view of my dike, and I Fig.5 is a plan view thereof, both these latter views also showing thepractical application of my invention.

In carrying out the aim of my invention, I suitably erect the dike orbarrier, designated generally as 1, transversely of the streams bed andinclude a galvanized sheet metal plate or sheathing 2, after the fashionof a roof-sheathing. Said sheet metal or sheathing 2 is suitably securedor nailed to suitable horizontal members or stringers 3, in turnfastened or nailed to posts 4, suitably anchored in the ground, asclearly seen in Figs. 1 and 2 and braced as at 4:. In the ground at thebase of the structure, as thus erected, is suitably laid in anexcavation, a layer of concrete 5, forming a sub-base, this sub-base ofconcrete being designed primarily to guard against the overflowing watergetting down under the dike. Within the sub-base of concrete 5 aresuitably horizontally embedded wooden blocks 6 having one end exposed towhich is nailed as at 7, or otherwise fastened, the lower edge of thesheet metal sheathing 2.

A suitable sliding gate or closure 8 is pro vided for the opening andshutting of an opening 8 in the dike 1, to allow the passage of justenough water through the dike to relieve or guard against overflow. Thelaterally sliding closure or gate 8 is received and guided at its upperend below an oifset guide member 9 secured to the sheet 2; the bottomedge of said closure or gate is let into, and guided within alongitudinal groove 10 formed in the concrete sub-base 5, supporting theclosure.

From the foregoing it will be observed that the water is effectivelycontrolled.

A. dike embracing the general features of my invention may be adapted tobe positioned laterally, or at the side of the stream.

I claim In a dike of the character described, a subbase formed ofconcrete, a plurality of horizontally disposed wooden blocks embeddedwithin said base having one end exposed, a metal plate having acentrally disposed square opening secured to said blocks, an offsetguide member secured to said plate above said opening a groove beingformed within said base below said guide member, a gate slidably held bysaid guide member and groove whereby said gate may be actuated to exposesaid opening, a plurality of horizontally disposed stringers secured tosaid plate, a plurality of posts embedded adjacent to said base securedto said stringers, and a brace bar secured to each of said posts, allarranged as shown.

In testimony whereof I affix my signature, in the presence of twowitnesses.

ROBERT JACKSON.
